In Memoriam

Klaas Willem Jonker
† April 30, 2018

On Monday 30 April 2018, Wilko Jonker died after a long illness at the age of 58. He leaves behind a wife and two children. The Dutch military aviation and plastic modeling were his hobby and on this website he shared all the knowledge he has collected over the years. His hobby has been able to distract him from the persistent disease in his body until the last week of his life. The contacts with other hobbyists were a major support for him.

This website will be maintained by different people for as long as possible, so that other enthusiasts can continue to benefit from extensive content.


The Ansaldo SVA 10 was a two seat version of the successful Ansaldo SVA.5 bomber-scout. This aircraft was one of the best in its days.
The Ansaldo SVA.4 was the first version, soon followed by the SVA.5, which had an enlarged fuel-capacity and improved armament.

Spring 1918 two new versions were developed, the SVA.9 and the SVA 10. The first one was an unarmed trainer with a smaller range than the SVA.5.

The SVA 10 was an armed scout and saw action during the last period of the war. In the end over 2000 SVA's were built and they were used until the thirties.
